What is negative distance contact?

I was puzzled for a long time when I first saw the word "negative distance contact". Finally, I understand its true meaning-sex, sex, sexual intercourse, mating, sex, that ... and so on, look at the words I listed. One is the essence of ancient China language, the other is a vivid representative used in foreign languages, the other is a standard term in written language, and the other is a model. But on the whole, I still think this "negative distance contact" is really a word that combines the essence of ancient, modern and Chinese and foreign countries, elegant and popular, avant-garde and fashionable!

At the same time, I admire the friend (or organization) who invented this word, and even solved a problem that has puzzled me for more than ten years: in junior high school, the head teacher of our class and the grade math teacher asked us to compare a negative distance in a geometry class. This is a realistic problem. No matter whether we compare the distance with hands, feet, rulers and pencils, it can't be "negative". Unless we set an origin and a line segment on the paper and blackboard, we can draw a negative distance, but that is an empty symbol, not a real entity. Therefore, from that day on, this "negative distance" made me feel that this is an insurmountable mountain of knowledge. I thought that if anyone could match him, he would surely win the Nobel Prize in Physics.

But just after I learned about "negative distance contact", I untied this knot and felt funny: in fact, everyone can compare it ... which is somewhat ironic.

Then, I began to think about why such a word appeared out of thin air. First of all, it should be taboo, that is, avoid using words such as "sex, sex and sexual intercourse" in conversation or writing. I think this word was coined by China people themselves. Due to the bondage and imprisonment of traditional ideas, many people are still ashamed to talk about the word "sex", but use other words instead, such as "that".

Secondly, fashion and taste. Although words like "that" can play a certain taboo role, it is a bit tacky when used too much, and the word "that" is often used in other aspects of real life, sometimes causing confusion and jokes. I first saw the word "negative distance contact" in a fashion weekly. Its readers are young people, white-collar workers, petty bourgeoisie and so on. So such a word has its "mass base" and its "identity" and "taste" have been redefined-it is not a common saying, but an elegant vocabulary of young petty bourgeoisie. At the same time, I firmly believe that the person (or organization) who invented this word belongs to the category of petty bourgeoisie in terms of cultural level, social background and economic conditions. How to explain it? Well, I remember a tepid writer said in his book, "What is petty bourgeoisie? People who have nothing to do with eating and turning over some new words in the dictionary. " Of course, this writer is only talking about some phenomena, or some petty bourgeoisie hobbies, but I also think that the person (or organization) who invented this word must belong to petty bourgeoisie.
